Primary Applications
Optical Coatings: Ideal for micron- and nano-scale coatings on PET, acrylic, and glass where high refractive index and low film thickness are critical. Provides brilliant optical effects and surface enhancement.
Optical Inks: Perfect for creating fine-patterned optical elements, such as diffraction gratings, via screen printing, transfer, or embossing processes. Enables high-resolution and precise imaging.
Optical Adhesives: Suitable for bonding optical components in electronics and optics where clarity, refractive index matching, and long-term stability under harsh environments (high heat, humidity, thermal cycling) are required.
Form & Curing:
Available in both one-component and two-component systems for flexible formulation and storage. Cures via heat or with a suitable hardener at room temperature.
Recommended Use:
For specialized requirements, TR-1645 can be formulated with other high-index resins or nano-fillers to tailor optical properties for a broad range of industry-specific applications.
